Outline of Final Research Achievements

This study developed a new supply chain efficiency evaluation model that integrates network DEA and Input-Output analysis. Specifically, the following two analyses were conducted during the research period: (1) construction of a supply chain efficiency evaluation model by applying an Input-Output analysis model to a network DEA model; and (2) supply chain efficiency analysis of the electricity sector in 164 countries based on a multiregional Input-Output table. Two conference presentations were made in the last fiscal year regarding the analysis of (1) and (2). The research will be continued for publication in a peer-reviewed English journal.

Academic Significance and Societal Importance of the Research Achievements

新型コロナウイルスの流行、ロシアのウクライナ侵攻、台湾有事への懸念等を事の発端とし、近年、我が国周辺のグローバルサプライチェーンの脆弱性が憂慮される事態となっている。グローバルサプライチェーンの再構築がその機運の高まりを見せる中で、本研究が新たに導入した「サプライチェーンの生産効率性」という概念は、これまでの生産経済学における生産効率性の概念とは一線を画すものであり、サプライチェーンに定量的な評価基準を付与するという点において、政策的意義の極めて高いものであると考える。
